Module Requirements

Each DGM requires a 9-30 VDC NEC Class 2 power

supply. This is supplied to the DGM through pins 27, 51,

68, 69 on the D-Sub connection. Ground from this sup-

ply should only be connected to pin 70 of the D-Sub

connection.

I/O Setup

NOTE: Each DGM is set as the primary or secondary

DGM by setting the rotary switch (AG) position. See

Setup on page 14.

See the Digital and Analog I/O Overview sections begin-

ning on the following page for I/O setup details. See the

Primary DGM Pin Assignments and Secondary DGM

Pin Assignments sections beginning on page 10 for

individual pin assignments.

NOTICE

To avoid ground loops and noise immunity issues, do

not ground the shield of the D-sub connector cable.

The shield is already grounded through the mounting

screw on the base of the DGM. If using a breakout

board, do not make any connections to the pins with

ground symbols.
